采用三维热解碳微电极，研制了一种高灵敏度的普鲁士蓝基过氧化氢传感器。3D打印的多电极电化学电池可以在多个碳电极上同时进行高重复性的普鲁士蓝修饰。研究了氧等离子体预处理和沉积时间对普鲁士蓝电沉积的影响。研究了在磷酸盐缓冲液中加入μ M和μ M以下浓度的过氧化氢时，二维和三维传感器的安培响应。在搅拌条件下，三维热解碳微电极具有与流动注射系统相当的高灵敏度和0.16 μ M的检测限
A highly sensitive amperometric Prussian blue-based hydrogen peroxide sensor was developed using 3D pyrolytic carbon microelectrodes. A 3D printed multielectrode electrochemical cell enabled simultaneous highly reproducible Prussian blue modification on multiple carbon electrodes. The effect of oxygen plasma pre-treatment and deposition time on Prussian blue electrodeposition was studied. The amperometric response of 2D and 3D sensors to the addition of hydrogen peroxide in mu M and sub-mu M concentrations in phosphate buffer was investigated. A high sensitivity comparable to flow injection systems and a detection limit of 0.16 mu M was demonstrated with 3D pyrolytic carbon microelectrodes at stirred batch condition
